Martina Navratilova revealed on Monday that she has been diagnosed with throat and breast cancer.

Navratilova told tennis.com that doctors discovered she had an unrelated form of breast cancer during throat examinations.

“This double whammy is serious but still fixable, and I’m hoping for a favorable outcome,” Navratilova said in a statement to the website. “It’s going to stink for a while, but I’ll fight with all have I got.”

According to the WTA, Navratilova underwent testing after noticing an enlarged lymph node in her neck in November. The former world No. 1 will reportedly begin treatment this month.

The 66-year-old was previously diagnosed with breast cancer in 2010.

Navratilova is one of the most accomplished tennis players ever. She won 59 Grand Slam titles in a career that spanned over four decades.

The Australian Open reversed a policy that banned fans from wearing a shirt that says, "Where is Peng Shuai?"

The Chinese tennis player accused a former government official of sexual assault last year on social media. She has made few public appearances since making the accusations.

The WTA issued a statement in December that said there are concerns about whether Peng is free and safe.

During the Australian Open, fans were reportedly told to cover their "Where is Peng Shuai?" shirts after protesting.

Tennis Australia has a policy that bans "banners, signs or clothing that are commercial or political."

Facing backlash, however, Tennis Australia CEO Craig Tiley told Agence France-Presse (AFP) that fans could wear the shirts.

"As long as they are not coming as a mob to be disruptive but are peaceful," he said.

The Australian Open is the first grand slam tennis tournament of the year.

It wraps up on Jan. 30.

A game from the end of his bid for what would have been the first calendar-year Grand Slam in men's tennis since 1969, Novak Djokovic covered his face with a towel, hiding his tears during a changeover. For 27 Grand Slam matches in 2021, on hard courts, clay courts and grass, Djokovic could not be deterred, could not be beaten. Needing one more victory, in the U.S. Open final Sunday against Daniil Medvedev, to complete a season sweep of major titles and to claim the record 21st of his career, Djokovic could not come through.Outplayed by someone using a similar style to his own, Djokovic came up just short of those two historic milestones, losing 6-4, 6-4, 6-4 to first-time major champion Medvedev at Arthur Ashe Stadium.What was in Djokovic's thoughts as he sat there on the sideline, knowing full well that his quest was moments from its conclusion? "Relief. I was glad it was over, because the buildup for this tournament, and everything that mentally, emotionally, I had to deal with throughout the tournament in the last couple of weeks, was just a lot. It was a lot to handle," Djokovic said at his news conference. "I was just glad that, finally, the run is over. At the same time, I felt sadness, disappointment — and also gratitude for the crowd and for that special moment that they've created for me on the court."Until Sunday, the No. 1-ranked Djokovic had been sublime at the sport's four most important tournaments, enduring the burdens of expectations and pressure over the past seven months and, in New York, the past fortnight.He won the Australian Open in February, beating Medvedev in the final in straight sets, the French Open in June and Wimbledon in July, pulling even with Rafael Nadal and Roger Federer at 20 Grand Slam titles, the most for a man in the history of a sport that dates to the 1800s. The last man to complete a true Grand Slam by going 4 for 4 at the majors in a single season remains Rod Laver, who did it twice — in 1962 and 1969 — and was in the stands Sunday. The last woman to accomplish the feat was Steffi Graf in 1988.Instead, Djokovic joins Jack Crawford in 1933 and Lew Hoad in 1956 as men who won a year's first trio of Grand Slam tournaments and made it all the way to the U.S. Open final before losing."I do feel sorry for Novak, because I cannot imagine what he feels," said Medvedev, a 25-year-old from Russia who had been 0-2 in major finals. "Knowing that I managed to stop him, it definitely makes it sweeter, and brings me confidence for what is to come."Djokovic, a 34-year-old from Serbia, simply was far from his best on this particular day."Just energy-wise, I felt slow," said Djokovic, who could not create the kind of comeback he had in each of his previous four matches — and six others in Grand Slam action this year — when he dropped the opening set. "I know I could have, and should have, done better," he said.Djokovic made plenty of mistakes, 38 unforced errors in all. He wasn't able to convert a break chance until it was too little, too late, going just 1 for 6. He showed frustration, too, destroying his racket by pounding it three times against the court after one point, drawing boos from the crowd of 25,703 and a code violation from chair umpire Damien Dumusois.A lot of Djokovic's issues also had to do with the No. 2-ranked Medvedev, who used his 6-foot-6 (1.98-meter) frame to chase down everything and respond with seemingly effortless groundstrokes — much the way Djokovic wears down foes — and delivered pinpoint serving. "He was amazing. Just congratulate him, full credit from his mentality, his approach, his game, everything," Djokovic said. "He absolutely was the better player and deserved to win, no doubt about it."Medvedev won 20 of his first 23 service points, establishing a pattern. He finished with 16 aces and 38 winners in all, 11 more than Djokovic. And Medvedev employed a strategy his coach, Gilles Cervara, described as hitting more balls down the middle of the court, rather than trying to find angles that would Djokovic to pick up balls on the run."He's so good that every match is different. He changes his tactics, he changes his approach," Medvedev said about Djokovic. "I had a clear plan, which did seem to work. Was he at his best? Maybe not today. He had a lot of pressure," Medvedev said. "I had a lot of pressure, too."Nerves, distracting noise from spectators and cramps that started in his legs got to Medvedev at the very end. He served for the match at 5-2 and was a point from winning before double-faulting twice in a row. At 5-4, he had a second match point and double-faulted again. On the next chance, though, a 129 mph service winner finally finished the job, and Medvedev toppled over to the court on his side with his tongue hanging out, which he explained afterward was inspired by a goal celebration from a soccer video game. During the trophy presentation, Medvedev addressed Djokovic, offering praise for "what you accomplished this year and throughout your career" and adding, "I never said this to anybody, but I'll say it right now: For me, you are the greatest tennis player in history." In recent years, there has been constant discussion and debate about which member of the so-called Big Three — Federer, who turned 40 last month, Nadal, 35, or Djokovic — deserves to be considered the best of the bunch and the "GOAT" ("Greatest of All Time").Even with Sunday's setback, Djokovic has accumulated statistics that help people make the case for him. He is the only one of that dominant trio to have won four majors in a row across two seasons, in 2015-16. He is the only one with at least two titles at each major tournament. He is the only player who has won each of the next-tier Masters 1000 events at least twice, too. He has spent more weeks than anyone at No. 1 since the ATP computerized rankings began in 1973, surpassing Federer for that accolade in March. And he holds the edge in head-to-head matchups against both of his long-time rivals. After a five-set win over Tokyo Olympics gold medalist Alexander Zverev on Friday night, Djokovic looked ahead to what awaited in the final and declared, "I'm going to put my heart and my soul and my body and my head into that one. I'm going to treat the next match like it is the last match of my career."But Medvedev, who lost only one set in the entire tournament, never allowed Djokovic to get into this match.From the start, Djokovic was not quite himself. After flubbing three break points early in the second set, the last with a sliced backhand in the net, he pounded his racket against his thigh — one, two, three, four times, perhaps as disappointed in his footwork as his form.Thousands in the audience tried to boost him by chanting his nickname, "No-le! No-le! No-le!" After some of Medvedev's faults, some in the stands would applaud, considered poor form in tennis and repeatedly admonished with a "please" from Dumusois.By the end, the deficit grew too large for Djokovic, the climb too steep."I was below par with everything, to be honest," he said. "So just one of these days where, unfortunately, wasn't meant to be."

WIMBLEDON, England —

The Wimbledon final was locked up at a set apiece after nearly 2 1/2 hours, and Novak Djokovic’s bid for a record-tying 20th Grand Slam title was at a critical juncture, when he faced two break points while thousands in the full-capacity crowd at Centre Court chanted his opponent's first name.

Bothered, perhaps, by the challenge he was facing between the lines Sunday, and, perhaps, by the support being thrown behind Matteo Berrettini, and, perhaps, by the weight of the milestone he was pursuing, Djokovic shrugged all of that off and steeled himself, as he’s done so many times at so many moments on so many stages.

On each of the next two points, Djokovic, known for his baseline supremacy, charged forward. On each, Berrettini’s passing attempt found the net. After the second, Djokovic stared into the stands and pointed to his ear, then waved his racket. He got what he wanted; a chorus of his nickname broke out: “No-le! No-le!” Two points later, when he grabbed the game with a 118 mph ace, Djokovic put his racket behind an ear, heard more noise, nodded and smiled.

An hour later, the match was finished — Djokovic won 6-7 (4), 6-4, 6-4, 6-3 — and so, too, was his stated desire to equal the total of major championships collected by his biggest rivals, Roger Federer (who reached 20 in 2018) and Rafael Nadal (who did it last year). No other male tennis player has more than 14.

Djokovic, of course, wants more.

“I consider myself best, and I believe that I am the best, otherwise I wouldn’t be talking confidently about winning Slams and making history,” said Djokovic, a 34-year-old from Serbia who is ranked No. 1 and has spent more weeks in that top spot than any other man. “But whether I’m the greatest of all time or not, I leave that debate to other people.”

It is a popular topic, certainly. And every member of the so-called Big Three has his supporters. This season might tilt the balance in Djokovic's favor in the minds of those yet to be convinced.

Already the first man since Rod Laver in 1969 to win the first three major tournaments in a year, Djokovic will take aim at a true calendar Grand Slam at the U.S. Open, which starts Aug. 30. Only two men — Don Budge in the 1930s and Laver twice in the 1960s — have gone 4-for-4.

“I’m going to definitely give it a shot,” Djokovic told the Centre Court crowd during the trophy presentation. “I’m in a great form and obviously playing well. ... So let’s keep it going.”

He earned a third consecutive championship at the All England Club and sixth overall. Those go alongside nine at the Australian Open, three at the U.S. Open and two at the French Open.

“I have to pay a great tribute to Rafa and Roger. They are legends. Legends of our sport. They are the two most important players that I ever faced in my career," Djokovic said. “They are, I think, the reason that I am where I am today. They’ve helped me realize what I need to do in order to improve, to get stronger mentally, physically, tactically.”

Federer and Nadal both tweeted their congratulations.

This was Djokovic's 30th major final — among men, only Federer has played more, 31 — and the first for Berrettini, a 25-year-old from Italy who was seeded No. 7.

“Hopefully,” Berrettini said, “it’s not going be my last one.”

It was a big sporting day in London for his country: Italy's soccer team faced England at Wembley Stadium in the European Championship final at night.

With Marija Cicak officiating, the first female chair umpire for a men's final at a tournament that began in 1877, play began as the sun made a rare appearance during the fortnight, the sky visible in between the clouds.

The opening game featured signs of edginess from both, but especially Djokovic, whose pair of double-faults contributed to the half-dozen combined unforced errors. He faced a break point but staved it off.

“Definitely,” Djokovic acknowledged, “felt slightly more nervous than I usually feel.”

The 6-foot-5, barrel-chested Berrettini's powerful serves sent line judges contorting to get their head out of harm's way. Djokovic occasionally took cover himself, crouching and raising his racket as if it were a shield to block back serves aimed at his body.

Not many opponents manage to return serves at 137 mph and end up winning the point, but Djokovic did that at least twice. And the big forehands Berrettini drives past most other players kept coming back off Djokovic's racket.

“I didn't play badly because I didn't feel well," Berrettini said. "He made me play badly.”

That's what Djokovic does: He forces foes to work so hard to win every point, let alone a game, a set, a match.

Indeed, this one could have been over much sooner: Djokovic led 4-1 in the first set, 4-0 in the second and 3-1 in the third. But in the first, he faltered, wasting a set point at 5-2, getting broken when he served for it at 5-3, then dropping four of the tiebreaker's last five points.

When Berrettini closed it out with a 138 mph ace, he shouted — but said later he couldn't hear his own roar because of the how loud many of the 15,000 spectators were.

But Djokovic is nothing if not a fighter. He blunted Berrettini's best efforts and won the fans over, too. When it was over, Djokovic dropped to his back on the turf, arms and legs splayed, showered by cheers. Moments later, he rose, threw his head back, spread his arms and basked in the joint appreciation of his accomplishment.

As Berrettini put it: “He’s writing the history of this sport, so he deserves all the credit.”

It was an entertaining final, with some magical points. On one, Berrettini conjured up a 'tweener lob that Djokovic tracked down with his own-back-to-the-court flick that wound up in the net. On another, Djokovic slid into a keep-the-point-going defensive backhand and, after Berrettini replied with a drop shot, sprinted forward for a winner. Djokovic raised his index finger — as if to remind everyone, “I’m No. 1!” — and Berrettini flipped his racket end over end, caught it and smiled.

What more could he do?

Not much anyone can do against Djokovic, it seems.

He has won eight of the past 12 majors — all since turning 30. And for all of the questions about when the younger generation would step forward, Djokovic is singlehandedly holding off the kids.

In this year’s three majors, he is 21-0, with victories in finals over Daniil Medvedev, 25, in Australia, Stefanos Tsitsipas, 22, in France, and now Berrettini, 25.

On Sunday, Djokovic made merely 21 unforced errors, while accumulating 31 winners.

Djokovic’s returns are as good as anyone’s, ever. His two-handed backhand is a constant threat. His ability to anticipate and reach shots is remarkable. And he does whatever it takes: Djokovic won 34 of 48 points when he went to the net, 7 of 9 when he serve-and-volleyed.

What sets him apart above all is a quality stats can't trace: “The ability to cope with pressure,” he called it.

When the tension and heart rate ratchet up, Djokovic is either impervious to that sort of thing — or plays as if he is.

It's the experience. The grit and guts. The talent and hard work.

This has been a year of dominance by Djokovic, on top of a decade of success.

“The last 10 years has been an incredible journey,” he said, “that is not stopping here.”
